Inglenook Shunting Puzzle

For those unfamiliar with the #Inglenook shunting puzzle, here's a quick guide.
The challenge is to make up a train of 5 wagons with suffices 1,2,3,4 &5.
Suffix numbers are randomly assigned at the start of each game.
The 2 top sidings can each hold 3 wagons max.
The bottom siding can hold up to 5 wagons.
The head shunt can hold the loco and 3 wagons max.
Ignore the letters on each wagon for now.
In game play, they identify the SNES controller buttons for (un)coupling.
